SPECIFICATION forming part of Letters Patent No. 291,577, dated January8, 1884.

Application filed October 13, 1883. (No model.)

To aZZ whom it may concern:

Be it known that I, NATHAN COLEMAN, a citizen of the United States,residing at Oneida, in the county of Nemaha and State of Kansas, haveinvented a new and useful Cultivator, of which the following is aspecification, reference being had to the accompanying drawings.

This invention relates to cultivators arranged to be used in hoeing orcultivating two or more rows of corn'and the like; and it has for itsobject to provide means possessing superior advantages in point ofsimplicity, durability, inexpensiveness, and general efficiency. In theaccompanying drawings, Figure 1 is aperspcctive view of my improvedcultivator. Fig. 2 is a longitudinal vertical section of the same. Fig.3 is a transverse section through the slotted cross-beam; and Fig. 4 isa detached view, showing the attachment of the plow-beams to the slottedbeam.

Like letters refer to corresponding parts in the several figures.

Referring to the drawings, A designates the axleof a wheel-cultivator,provided with the usual wheels, B B, and a tongue, 0. To the top of thelatter is secured a beam, D, slotted at each end, as shown at E, bailsor yokes F being held in the slots of said beam at each end by means ofsuitable bolts and nuts, G H.

It will be seen that byloosening the bolts and nuts the bails can beadjusted at varying distances within slots E, said bolts and nuts beingtightened when the adjustment has been effected, and securely holdingthe bails from accidental displacement.

I I designate plates secured to the top and bottom of the plow-beams J,at the front ends of the latter, said plates projecting forward, andprovided with hexagonal blocks K, two in number, the latter beingconnected together by bolts between the front ends of the plates I. Theblocks are formed with grooves i, to receive the yokes or bails F, andin operation it will be seenthat the blocks permit the plow-beams to belifted vertically from off the ground,while the pivotal connection ofthe plates I to said blocks allows the lateral movement of theplow-beams. ployed to effect these movements are exceed The means emingly simple and not likely to get out of order.

The plow-beams J J are provided with the ordinary handles, L, and at theouter or rear end of said beams are attached standards M, which projectdownwardly therefrom, a crosspiece, N, being secured to the front faceof the standards and connecting the same. Plow feet or standards 0 areattached to the crosspiece at each end, the latter being slotted at o,to permit ready adjustment of the plowfeet to suit varying widths ofrows. Shovelplows P are adj ustably attached to the lower end of theplow-feet, as shown, any suitable plow being used for this purpose.

Q Q designate rods or bars attached to the standards M, and providedwith a notch or recess, 0, at their upper ends, an eyebolt, B, beingjournaled in the plow-beams J, and having its ends r turned at rightangles, so as to engage with the recess 0 in the bars Q, and thus lockthe same. These rods or bars Q serve not only as braces for thestandards M, but also-act to hold the plows at a certain depth orinclination in the ground, this inclination being varied as desired. vThe operation of my invention is obvious, and need not be particularlyrecited here. Since each plow-beam is separate and distinct from theother, any variation in the width of the rows of corn need not affectits operation, since the plow-beams and the plow-feet are arranged toprovide for this, as above de scribed. Each plow-beam, with itsattachments, cultivates a distinct row of corn, and for the same purposeas many more beams may be added as found desirable.

It will be apparent that various modifica tions maybe made in theforegoing without departing from the spirit or scope of my invention.

Having described my invention, I claim as new- 1. In a cultivator, thecombination, with the slotted beam D, provided with yokes or bails F,secured to the same in the manner shown, of the plow-beams J, providedwith plates I at their front ends, said plates connecting apair ofblocks, K, between the same, the blocks being formed with grooves i, toreceive the yokes or bails, said parts being arranged to permit thevertical and lateral ends, and plow-feet adjustable in the slots ofmovement of the plow-beams, as set forth. said cross-pieces, as and forthe purposes set 2. In a cultivator, the plow-beams having forth.standards M projecting downwardly there In testimony that I claim theforegoing as 5 from, in combination with the rods Q, atmy own I havehereto affixed my signature in 15 taehed t0 the standards and providedwith presence of two Witnesses.
